Application October-30, 193e, SerIalNo. 108,347

2 Claims. (Cl. 132-362) This invention relates to improvements in permanent wave pads and more particularly to a permanent wave pad and modified forms thereof,

adapted to be used in the pre-heating system of permanent waving as well as conventional methods.

An object of the'invention is to provide a permanent wave pad which will have features of economical manufacture not' found in similar devices of the type now in use.

\ Another object of the invention is to provide a pad having qualities of high heating retention I not foundin similar products of the type-hitherto in use.

Another object of the invention is to provide a permanent wave pad constructed of a combination of materials which can be formed'into units more economical than is possible with the materials now employed in'similar. devices of a like description.

Other and further objects of the invention will I appear as the description proceeds, reference being had to the accompanying drawing in which:

' Fig. 1 is a view 'in perspective of a permanent wave pad embodyingmy invention.

' Fig. 2 is a vertical, sectional, fragmentary view of a preferred form of the device.

Figs. 3, 4, '5, and 6 are similar views of modified forms of my invention.

Fig. 7 is a plan view of another modified form.

'Fig. 8 is an end view of a permanent wave pad in bent form. I F

Referring more particularly to the drawing, the numeral I represents the permanent wave pad generally, having the cover member I l and-the base member l2.

In the formshown in Fig. 2, a base member rectangular in form, consists-of a paper material having an absorbentqualityin a limited degree. The cover member II in this example is formed of a relativelynon-absorbent paper. The member II is adhesively secured throughout its area to a surface of the base portion l2. In the operation of formingv permanent waves in hair dressing, the hair is separated into strands by an operator, and wound around a conventional winder or spacer well known to the trade. De-

, vices of the type of the present invention are then wrapped or placed over the wound portion of the'hair strands, and in turn are engaged 'within a clamp means containing a heated or heating element. It is customary in practice to apply a preparation usually of an unctuous char-v acter. It will readily be understood that the base portion l2 of paper having an absorbent ability will be favorable to the retention. of such a preparation. In the modified form shown in Fig. 3, a metal foil, preferably aluminum foil, is used to cover the absorbent paper, and has high heat retention value.

In the form shown in Fig. 4, the asbestos composition forming the base member is highly retentive both of heat and of oily preparation which may be used in the operation.

As in Fig. 5, the asbestos composition may be .covered with a paper member H having little or 'no absorbent function. It will be found desirable to use a fabric covering II as in Fig. 6, as a further modification.

The pads l0 may be cut rectangularly as in Fig. 1, or may be indented arcuately at the ends thereof as in Fig. '7, for greater facility in wrapping the same about the winders and spacers.

, .It will be understood that the invention is capable of many modifications in structure and design, without departing from the spirit of the invention, all within the scope of the appended claims. e I

A further modification comprises a double pad consisting of two base members, one of asbestos composition, and one of absorbent paper, and two cover members of metal foil, the whole being fastened together at one of the 'marginal edges thereof as by sewing. This form affords the user a choice as the pads may be torn apart.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States is: g

1. A device of the' class described comprising a rectangular base member formed of absorbent paper, and an identical cover member of nonabsorbent paper adhesively secured throughout its area to said base member.

2. A device of the class described comprising a rectangular-base member formed of paper having a limited absorbent quality, and an identical cover member of non-absorbent paper adhesively secured throughout-its entire area to said base member.
